Application February 16, 1934 Serial No. 711,606 '6 Claims. (01. 118-59) My present invention relates to spinning rings for use on textile spinning machinery and particularly to means for lubricating the ring, whereby during a relatively long spinning operation the ring will be continuously lubricated.

In the accompanying drawing, I have shown several embodiments or forms 'ofmy present invention all adapted to the attainment of the same end, and the objects and advantages of the invention will become apparent and will be pointed out during the following detailed description of the accompanying drawing, in which r I Fig. 1 is a vertical transverse sectional view through a spinning ling embodying one form of my invention, and the base or support therefor and a fragment of aframe;

Fig. 2 is an enlarged fragmentary sectional view through the spinning ring and base shown in Fig. l; g I

Fig. 3 is a view similar to Fig. 2 showing another form of ring and traveler;

Fig. 4 is a view taken on the line 4-4 of Fig. 2;

Fig. 5 is a perspective view of one form of means for clamping a lubricating wick in place;

Fig. 6 is an elevation partly in section of the device shown in Fig. 5 with means for drawing the arms thereof together to grip the wick;

Fig. 7 is a perspective View similar to Fig. 5 of another form of lubricating wick; and

Fig. 8 is a view simiar to Fig. 3 showing a modification in the ring, wick-and clamping means therefor.

Referring to the drawing and particularly to Figs. 1, 2 and 4, the numeral 9 designates a frame on which the lateral fiange ID of the base or support for the spinningring is mounted, said flange having upstanding clips II at its outer edge, and an upstanding annular flange I2 at its inner edge, the clips II being provided to receivethe downturned edge of the lateral flange I3 of the spinning ring to connect the parts for a spinning operation.

absorbing and containing lubricating oil.

:and between which ends is provided an annular channel, including the grooves in said ends, around the ring to receive a wick I! of absorbent material. 'I'hewick I! may be formed of any suitable flexibleaabsorbent material capable of At preferably regularly spaced intervals the wall I5 is provided with openings I8. A clamping band or'wire I9 may surround the wick and be drawn together at its ends either by twisting said ends around each other, orby separate means present- 5 1y described, so as to draw the wick tightly against the 'wall I5, whereby oil may exude through the openings I8 and be drawn therethrough by the rapid rotation of the traveler T. Thus the surface of the ring which is contacted in by the traveler T during its rapid rotation will at all times be lubricated, assuring smooth action and minimizing wear. Obviously, the operator or attendant may from time to time if necessary saturate the wick with more oil.

'In Fig. 3 the embodiment of the invention is substantially the same as that shown in Figs. 1,

2 and 4, and the primed numerals of Fig. 3 indicate the same parts as uprimed numerals designate in Figs. 1, 2 and 4. It will benoted that in 20 Fig. 3 instead of having the wall =I5 of the ring arranged substantially in a plane vertical to the plane of the flange I3 that the metal is so bent that thewall i5 is inclined at an-angle of substantially 45 or 50 to the plane of the flange I3 25 and instead of ring traveler T I have shown a bar traveler 2i. This inclination of course arranges the grooved ends I4 and I6 also at an inclination, and consequently arranges I the annular channel around the wall I5 and. the wick therein atthe same angle of inclination. The wick may be held in the channel by the same means disclosed in Figs. 1, 2 and 4, a simple form of which will now be described. I

Referring to Fig. 5, a wire is shown in perspec- 5. tive provided with inwardly directed projections 22 corresponding in number and relative spacing to the number and relative spacing of the openings I8 and I8 in the walls I5 and I5 of the ring above described. The wire is bent to 40 provide a loop 23 at its approximate center to give itia spring action. The ends of the wire may be. bent outwardly as at 24 and looped as at 25, which loops may be internally screw threaded as shown in Fig. 6 to receive a screw 26 to draw the 45. ends of the wire together and consequently force the projections 22 againstthe wick at the openings I 8,'I8- so'that the wick will extend well into the openings as shown in Fig. 4, facilitating the feeding of the oil to the inner surface of 50 the rings. It is quite obvious, and I think need not be illustrated, that the loops 25 need not necessarily be screw threaded. and that a nut may be applied to the screw 26 and turned to draw the ends together. Also as above mentioned, the 55 loops may be omitted and the ends of the wire may be twisted about each other to draw the wire tightly against the wick to hold it in place and force portions of the wick into the openings in the ring.

In'Fig. '7 I have shown another type of wick embodying a wire core which may be made in several manners, such as by inserting a wire through a tubular knitted fabric or by twisting the wires about strands in known manner to provide a fabric exterior surface 3. Under such forms of wick it would not be necessary to provide the separate clamping wire and separate wick as in Figs. 1-4, because the wick of Fig. 7 would simply be inserted in the channel between the ends M and IE, or I4 and I6" against'the inner face of the walls l5, l5 and drawn tightly thereagainst either by threading the loops 21 on the wire core the same as in Fig. 6 orby twisting the ends of the wire about each other arty means of anut andscrew-as previously described. The lubrication of the wick shown in Fig. 7 would be the sameas in the case of the wicks described in theother figures, namely, by saturating it with oil from time to time as necessary. v

In Fig. 8 I have shown still a further modification of the invent-ion in which the ring is formed from a single blank of metal'as in the otherpases to provide lateral annular flange 28, corresponding to the flanges I3 43', supported-by the-clips i? which are formed as a partof the base 10". The ;metal is bent downwardly from the. flange 2-8 asv at '29 and then upwardly upon itself as :at -30 but-is not bent outwardly and'downwardly at its top, the inclined ring surface 3! being rounded off at its upper end 32. .Openings 33 corresponding to=openings 18, +8 are provided in the wall 3i just above or at the innerrend of the lateral flange 28: r In connection with this type of ring, I may :provide a flatcircu-lar wick 36 to rest on the top'of the flange 28, and the wick,-i-f desired, may be clamped thereon by any suitable means, such as a wire or perforated metal split disc -35 having dependingarmstfi which'inay be engaged under the shoulders of the clips l2. The wick 34 should terminate or abut at its inner surface against the outer surface'of :the wall 3 I and openings-33 of the ring. Oil could be-supplied to the wick from time to time by :pouring thereon -or by means=of an oil can, sothat 'it could escape in the manner above described through the open ings 38 to the inner surface-of the ring 31.

It should ;be apparent from the foregoing :that all forms of the invention provide a ring which may bepreferablyand easily madeof a single-piece of metal provided with a smooth surface on which either ring or bar travelers travel for the spinning operation, and having on its exterior a lubricating wick to supply the 'oil through the openingsand capable of being readily resaturated from time totime without stopping thespinning operation. The number of openings through which oil is fed to the inner surface is optional, and the size thereof preferably relatively small.
